ASH-SIFTER.

Specification of Letters Patent.

Patented Apr. 13, 1920.

Application filed September 24, 1919. Serial No. 326,041.

To all whom it may concern:

Be it known that I, ADAM KoLAR, a citizen of Czecho-Slovakia, residing at Millfield, in the county of Athens and State of Ohio, have invented certain new and useful Improvements in Ash-Sifters, of which the following is a specification.

The primary object of the present invention resides in the provision of an ash sifter in which the agitation of the ashes in passing through the machine is incased at all times with the refuse falling to an inclined guideway directed laterally of the machine while the cinders pass from the end of the machine.

A further object of the invention is to provide an ash sifter whereby the ashes upon being introduced into a hopper are agitated and delivered upon a laterally shifting screen manually operated to remove all ashes from the cinders and to separate the same during the sifting movement.

Vith the above and other objects in view, the invention consists in the novel form, combination and arrangement of parts herein fully described and shown in the accompanying drawings, wherein like reference characters indicate similar parts throughout the several views.

In the drawings,

Figure 1 is a longitudinal sectional view of an ash sifter constructed in accordance with the present invention, a part of the hopper being broken away to-illustrate the agitator therein,

Fig. 2 is a horizontal sectional view taken on line 11-11 of Fig. 1 showing the laterally positioned crank shaft for operating the agitator and vibrating the ash sifter,

Fig. 3 is a vertical sectional view taken on line 11 III of Fig. 1 showing the link connection for laterally shifting the ash chute, and

Fig. 4 is a detailsectional view showing the supporting members for the laterally shifting ash chute.

Referring more in detail to the accompanying drawing, there is illustrated a casing supported upon four corner legs 5, the casing including side walls 6 and upper wall 7 with the side walls and upper wall extending upwardly at the receiving end of the casing to provide an enlarged chamber 8 formed by the upper inclined wall 7', the rear wall 9 and the cover 10, there being provided a skeleton frame for supporting the walls above described. As shown in Fig. 1, the cover 10 is provided with a hinged door 11 closing an entrance opening and retained in closed position by a latch 12.

A pair of transverse bars 13 are supported at their opposite ends upon the longitudinal members 14 of the casing frame and carry upstanding brackets 15 having bearings 16 formed at the upper ends thereof co6perating with the bearing 17 arranged at the end wall 9 of the casing for supporting a crank shaft 18, the crank shaft 18 being provided with a handle 19 exteriorly of the casing wall 9 for rotating the same. A pair of levers 20 are carried by each cross bar 13 in longitudinal alinement at the center of the cross bars and each pair of levers being pivoted as at 21 to the cross bars while the upper ends thereof are pivotally connected as at 22 to a cross head 23, and as shown in Figs. 1 and 3, the cross heads 23 have a pitman connection with crank portions 24 of the crank shaft 18, the pitmen 25 being pivoted as at 26 to the cross heads 23 and having a strap connection 27 at their opposite walls to said crank portions 24. As shown more clearly in Figs. 3 and 4, each cross head 23 carries a depending cage 28 within which is journaled a vertical roller 29 adapted to be engaged by the blocks 30 carried by the cross bars 13 and arranged at the outer sides thereof.

A receiving hopper 31 is connected at its upper end to cross beams 32 beneath the cover 10, the same being open at its lower end and telescoping within a depending hopper 33 carrying brackets 34 which,are pivotally supported upon arms 35 carried by the hopper 31, the hopper section 31 being rigidly mounted while the hopper section 32 is permitted to move upon its ivotal connection 34 and 35 in laterally swinging directions. An ash chute 36 is positioned beneath the hopper section 32 and has an open end into which the hopper section 32 extends, the chute 36 being secured to the cross heads 23 connecting the pivoted levers 20 and being movable therewith while the bottom wall of the chute 36 is reticulate as at 37 to permit fine particles of the ashes to be sifted therethrough.

An agitator is positioned in the hopper section 31 and includes a shaft 38 journaled in the opposite walls of the hopper 31 and carrying a fin er 39 inwardly of the hopper while a crank 40 is formed on the shaft 38 eXteri-orly of the hopper 31 and has a pitman connection 41 with the crank portion 42 of the crank shaft 18.

The cross beams 43 of the casing frame support a laterally directed inclined ash chute 44 discharging refuse laterally of the machine while the forward end of the machine beneath the upper wall 7 has a cinder receiving inclined chute 45 freely open at its forward end and provided with a rear wall 46 having an opening 47 therein through which opening the forward end of the ash chute 36 projects.

Inthe operation of the device, the closure 11 is removed by releasing the latch 12 ashes delivered into the hopper 31 after which the closure 11 is secured in position to prevent the escape of ashes and dust at this point. The crank handle 19 is then operated for turning the crank 18 and by the pitman connection 31 between the crank portion 42 ofthe crank shaft and the crank portion 40 to the agitator shaft 38', the finger 39 is? swingingly oscillated within the hopper 3-1 for purposes of agitating the ashes contained therein. Simultaneously, with this movement of the agitator, the crank portion of the shaft 118 communicates a reciprocatory motion to the cross head of the levers 20 which cross head supports a reticu lated ash chute 36, communication between the hopper 31 and chute 36 being constantly maintained by the pivotal hopper section 32. During this movement, the ashes and refuse within the chute 36 will fall through the reticulated bottom wall into the laterally directed inclined delivery chute 44 while the cinders and underburnt coals in the ashes will be delivered through the open forward end of the chute 36 into the inclined pass geways 45 for delivery from the end of the machine. In this manner, the ashes and ref- 7 use is carefully separated from the cinders and unburnt coals and thedust and floating ashes maintained within the casing.

While there is herein shown and described what is believed to be the preferable embodirnent of the invention, it is nevertheless to beunderstood that minor changes may be made in the form combination and arrangementof parts without departing from the spirit and scope of the invention as claimed.
